A Milestone for Zero-Carbon Multifamily Housing
The Bridge District’s holistic approach goes beyond designing for the individual and the community, but for the planet through its emphasis on sustainability and decarbonization. With a focus on reducing both operational and embodied carbon, Phase One is on track to become the largest ILFI Zero Carbon multifamily residential building in the world and the first in the DC region. The building is all-electric and powered by renewable energy generated via a rooftop solar array and off-site sources, an achievement that aligns with the District’s goal of electrifying all new homes and commercial buildings by 2032. Solar analyses influenced the building’s orientation, massing, and glazing, resulting in an anticipated 30% energy reduction over baseline. The design team worked with Redbrick LMD and HITT Contracting to reduce the carbon emissions associated with the building’s structure, envelope, and interiors. The team used ZGF’s open-source Concrete LCA tool to calculate and compare the carbon impacts of proposed concrete mixes for the building’s structure, while EC3 helped the team measure the whole building emissions. The project is tracking a 37% reduction in embodied carbon. Furthermore, the building encourages sustainable transportation by providing bicycle parking, a bike repair station, a bike wash, 20% electric vehicle charging stations, and proximity to public transportation.
As future phases of the Bridge District come to fruition, the development will continue to create opportunity and expand connectivity in an area that has been historically isolated from the rest of the District. This project paves the way for future developments to promote inclusive, sustainable, and healthy communities while taking credible climate action.
